Debt Ratios for Home Financing

Lenders use a ratio called "debt to income" to determine the most you can pay monthly after your other monthly debts have been paid.

How to figure your qualifying ratio

For the most part, underwriting for conventional mortgages needs a qualifying ratio of 28/36. An FHA loan will usually allow for a higher debt load, reflected in a higher (29/41) ratio.

The first number in a qualifying ratio is the maximum percentage of gross monthly income that can go to housing costs (including loan principal and interest, PMI, homeowner's insurance, property tax, and homeowners' association dues).

The second number in the ratio is the maximum percentage of your gross monthly income which can be applied to housing costs and recurring debt together. For purposes of this ratio, debt includes payments on credit cards, vehicle loans, child support, and the like.

Some example data:

With a 28/36 qualifying ratio

  • Gross monthly income of $3,500 x .28 = $980 can be applied to housing
  • Gross monthly income of $3,500 x .36 = $1,260 can be applied to recurring debt plus housing expenses

With a 29/41 (FHA) qualifying ratio

  • Gross monthly income of $3,500 x .29 = $1,015 can be applied to housing
  • Gross monthly income of $3,500 x .41 = $1,435 can be applied to recurring debt plus housing expenses
